Stone installation work involves the precise placement and securing of natural or manufactured stone materials, such as granite, marble, or limestone, for surfaces like countertops, walls, floors, or facades. The process includes measuring and cutting stone to fit specific dimensions, preparing the substrate, applying adhesives or mortar, and setting the stone with proper alignment and leveling. It requires skilled craftsmanship to ensure seamless joints, durability, and aesthetic appeal, often followed by sealing or polishing to enhance the stone's longevity and appearance.
